BOX-NAILING PRESS.

Specification of Letters Patent.

serial No. 792,910.

To all whom it may concern:

Be it known that I, WILLIS G. SNOW, a citizen of the United States, anda resident of Hood River, Hood River county, State of Oregon, haveinvented a new and useful Improvement in Box- N ailing Presses, oi whichthe following is a specification.

My invention relates to means facilitating the fastening of the cover ortop of that type of fruit boxes which are provided with transverse barson top, over which the cover is bent when fastened in place, so that thefruit will be protected from crushing and also be properly ventilated;and my invention particularly relates to the machines used for bendingthe box top over said transverse bars for holding its ends down whilebeing nailed on the body of the box.

The object of my invention is to provide a machine which will do thework mentioned quickly and will automatically release the box when thenailing process has been completed and the operating parts of themachine are released.

Another feature of my invention lies in the use of grappling devices forholding the box-top ends which will automatically adjust themselves,while being operated, so as to exert a uniform pressure on the ends ofthe box-top notwithstanding one or both of such ends are inclined fromthe horizontal. Without such automatic adjustment the grappling deviceswould be apt to exert an uneven pull and possibly break the cover, orimperfectly hold one or both ends of the boxtop on the body of the box.

The above mentioned and other incidental features are all hereinafterfully set forth.

In the accompanying drawings: Figure l shows a front elevation of mypress with the operating parts in their inactive positions. A fruit box,ready to be nailed up, is shown in place on the press table; Fig. 2 is alongitudinal vertical section of the press; this view illustrates thefurther action of the operating parts when the machine is operated topress the cover of the box down and hold it in such position while beingnailed; Fig. 3 is a transverse vertical section taken approximately onthe line 3 3 of Fig. 2, the fruit box being shown in broken outlines;and Fig. 4 is a larger-Sized detail of the automatically adjustableholder fingers; the broken lines of this figure show these lingers movedto another position.

My press machine comprises a table, a, the top of which is cut away asshown at a. This cut-away portion is of a length slightly greater thanthat of the smaller sized fruit box to be handled by my machine. Crossbars o located under the cut-away portion a form a support for the fruitbox. Said cross-bars, b, are connected by a longitudinal member al.Cleats, c, on the table top4 serve as a seat for guiding and holding afruit box of larger size.

On the member CZ is fastened a ring e, from which depends a coil-springf. Pivotally mounted between the end legs a2 of the table, a, are thetreadle bars g. The lower end of the coil-spring f is connected to saidtreadle bars by links g, tending to hold the latter in the positionshown in Fig. l.

On the treadle bars are fastened projection plates g2, the ends of whichsupport pendent pins L, and the latter support a horizontal plate L.pivotally mounted between the vertical struts a3 at the rear of thetable. Said foot treadle bears on the horizontal plate h and when it isdepressed the treadle bars g will likewise be depressed against thetension of the spring f.

The treadle is provided with a plate j, adapted to be engaged with theteeth of a ratchet bar Z, located at the front of the table, to hold thetreadle down. When the foot treadle z' is released from the ratchet theparts will be restored to their normal position by the action of thecoil-spring f.

A foot treadle z' isy In the top of the table, a, are provided i" and s,the upper ends of which are made with hands r2, s2, adapted to grip theends of the box cover. The parallel members 1^ and s are fastened on thecross arms p, Q by pins r', s', respectively, whereby said members areadapted for parallel movement. Thus when an end of the box cover is notin horizontal plane the members i" and s lwill adjust themselves to theinclination and permit the hands to bear down on the box cover with auniform pressure notwithstanding.

On the inner faces of the arms 7c are fastened the wedge shaped cams 0.When the box cover has been nailed down and the foot' treadle i isreleased, the arms 7s will be raised by the drawing up of the treadlebars g, and the parts are so relatively arranged that during such upwardmovement of the arms 7c the cams 0 will contact with the cross bars, andin so doing cause said grapple arms 7c to be moved outward-and therebyreleasing the latter from the fruit box. See Fig. l.

The front of the table, a, is cut away as shown at a5 (see Figs. 1 and3) so that the operator may thrust his arm underneath the box inremoving the latter from the table.

I claim:

1. In a box press, the combination` of reciprocable grappling arms alsoadapted for being moved laterally; manually operated means for operatingsaid arms; means for placing and holding the grappling arms in workingposition while being operated; and cam actuated means for moving saidarms out of working position while making their return movement.

2. In a box press, the combination of reciprocable grappling arms alsoadapted for being moved laterally; a treadle and connections foroperating said arms; means for placing and holding the grappling arms inworking position while being operated; and cam actuated means for movingsaid arms out of working position while making their return movement.

3. Ina box press, the combination of reciprocable grappling arms alsoadapted for being moved laterally; a treadle and connections foroperating said arms; a spring element for placing and holding thegrappling arms in working position while being operated; and camactuated means for moving said arms out of working position while makingtheir return movement.

t. In a box press, the combination of reciprocable grappling arms;grappling hands fastened on the extremities of the grappling arms; saidhands comprising two members spaced apart; and means pivotally connect-.ing said members to the grappling arms, said means permitting saidmembers to have independent movement in a line parallel to said arms.

5. In a box press, the combination of reeiprocable grappling arms;grappling hands -fastened on the extremities of the grappling arms; saidhands comprising two members located on either side of said arms; andmeans pivotally connecting said members to the grappling arms, saidmeans permitting said ymembers to have independent movement in a lineparallel to said arms.

6.

7. In a box press, the combination of reciprocable grappling arms alsoadapted for being moved laterally, means for placing and holding thegrappling arms in working position while being operated; and cams on theinner faces of said grappling arms, abutting surfaces for said cams,whereby said grappling arms are spread apart while being returned totheir inactive position.

8. In a box press, the combination of reciprocable-grappling arms alsoadapted for being moved laterally, means for placing and holding thegrappling arms in working position while being operated; cams on theinner faces of said grappling arms, abutting surfaces for said cams,whereby Vsaid grappling arms are spread apart while be- Y ing returnedto their inactive position; grappling hands fastened on the extremitiesof the grappling arms; said hands comprising two members spacedapart;and means connecting said members with the grappling arms and permittingsaid members to adjust themselves to an inclined surface.
